You can configure how the recommendations engine works by navigating to Quick-access menu > Plugins > Machine learning settings > Recommendation engine.
Remember to click Save changes when you have finished configuring these settings. The other settings on the Recommendation engine page are only used by the legacy recommendation engine, and will be deprecated in a future release.
The Recommendation algorithm and Processing threads configurations can be modified from their default values by setting environment variables before starting the Machine Learning Service, as described in the README.md file of the Machine Learning Service (integration/extensions/ml_service/README.md).
